Propeller Boss Cap / escap - Small cap. Big impact.

Little attention is paid to the propeller boss cap as part of the propulsion system. However, with a sophisticated design, also the propeller boss cap can contribute to increasing the efficiency of the ship's propulsion system. There are many possibilities.

Are you planning to build a new vessel or do you want to retrofit your existing fleet? We will be happy to advise you and develop a suitable solution with you.

With the innovative escap® (Energy Saving Cap) from MMG, shipowners can increase the efficiency of their ship propulsion systems by up to 3%. Unlike conventional propeller caps, the MMG escap® has an ingenious fin design that untwists the hub vortex and simultaneously reduces torque loss.

The MMG escap® propeller cap is not only suitable for newly built propellers. It is also the ideal solution to make existing propellers noticeably more efficient. And because the investment required is manageable, the return on investment can be achieved after a very short time.

MMG escap®: Fast installation. Worldwide service.

Whether as a retrofit for an existing propeller, in combination with a MMG redesign or as an extra as part of the construction of a new ship. MMG organizes and supervises the assembly of the escap® quickly and worldwide.

Your benefits:

Fuel saving of up to 3%
Very short ROI
Simple and fast installation
Reduced cavitation on rudder

An investment with multiple payoffs

As various model tests show, the average predicted savings potential for a 7,000 TEU container ship travelling between Asia and Europe with the MMG escap® is approx. 3%.

A calculation example:

At a vessel speed of 17 knots and a price for IFO 380 of 600 USD per ton, the application of a MMG escap® results in a reduction of operating costs of up to 96,000 USD for a single Europe-Asia round trip.

In addition, the optimized flow behaviour reduces cavitation on the rudder and hence reduces wear and maintenance costs.
